FRUIT-JAR.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed May 2, 1907. Serial No. 871,487.

To all whom it may concern:

Be it known that I, NOAH W. IsLnY, a citizen of the United States, residing at Newton, in the county of Jasper, State of Illinois, have invented certain new and useful Improvements in Fruit- Jars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to means for pressing and holding the covers for preserve-jars on the tops of the same.

In nearly all preserve-jars that are made of glass there is a yielding washer interposed between the top of the jar and the cover, and the latter is pressed down by the point 01' a screw tapper through the center of a yoke that engages the under side of the flanged top of the jar. While this form of means is efiicacious, a fault exists therein in that the covers are sometimes broken in turning down the clamp screw, owing to the rigidity of the latter and the clamp, which are made of rigid metal.

It is the purpose of my improvements to obviate the objection mentioned and at the same time provide a clamp that will be efficient to a maximum degree and ready and easy to manufacture, and be of little cost in its production.

The nature of the invention is fully and clearly ascertainable from the device portrayed in the annexed drawings, forming a part of this specification, in view of which it will first be described with respect to its construction and mode of use and then be pointed out in the subjoined claims.

Of the said drawingsFigure 1 is a perspective view of my invention applied. Fig. 2 is a similar view of the same detached.

Similar numerals of reference designate similar parts or features, as the case may be, wherever they occur.

In the drawings 3 designates the yoke which is composed of a length of wire having its middle portion bent laterally upon itself forming two recurvate bends 4 4, extending at right angles to the body portions 5 5 which extend upward and substantially horizontally across the top of the cover and then down at the opposite side where the end portions are bent laterally and doubled upon themselves so as to form bends 6 6 similar to the recurvate bends 4 4.

Both of the bends 4 and'G are inset so that they may take under the flange on the top of the jar or in a groove formed in the upper end of the jar.

At the center where the body of the wires cross the top of the cover they are curved outward in opposite directions, as at 7, leaving a rounded space between them for the passage of the shank of the clamp-screw S which is tapped through a nut 9 having an elongated head the top surface of which is formed to receive and maintain the wires thereon. The point or end of the screw is adapted to bear on the top of the cover.

In use, the wire portion of the device, which practically forms a yoke is engaged with the top of the jar as described and the nut 9 is arranged beneath the wires that extend across the top below the round opening '7 and the clamp-screw S is turned therein with the effect of pressing the cover of the jar down tightly and yet resiliently on the washer interposed between the cover and the top of the jar without any danger of breaking the former.

The resilient property of the clamping device results from the construction of the yoke of resilient wire, at the same time the structural characteristics of the clamp renders it an object that can bereadily manib factured at a very low cost.

The nut 9 can be made of low-cost metal and is easily produced by common workshop methods and means.

The strength and size of the wire will vary with the size of the structure.

What is claimed is- A clamp for closing preserve jars consisting of a length of wire doubled upon itself and having inset ends the wires at their center being rounded outward forming a rounded opening in the top. a clamping screw having its shank passed through said opening, and a nut through which the screw is tapped, the lower end of the screw extending beyond said nut.

In testimony whereof, I aflix my signature, in presence of two witnesses.

NOAH IV. ISLEY.
